Finally something really interesting to talk about. If you've used UNIX or any of its derivatives, you've probably wondered why there's /bin, /sbin, /usr/bin, /usr/sbin in the file system. You may even have a rationalisation for the existence of each and every one of these directories. The thing is, though - all these rationalisations were thought up after these directories were created. As it turns out, the real reasoning is pretty damn straightforward.

But as long as we recognize that we all have different needs, then we should be able to get along.

But we all do have the same needs, in the end. That's the problem. We all need to read data, convert them into native values, make computations on them, and convert them back to byte streams to save them on disk.

So much code is dedicated to saving and loading data...all this effort could have been saved for something better.
